Abstract (en)

[origin: US2021044820A1] A method includes receiving a bit stream; determining, using the bit stream and for a current frame, whether the current frame is available to be used as a reference frame; setting, in response to determining that the current frame is available to be used as a reference frame, a variable characterizing that an adaptive resolution management mode is disallowed; and reconstructing pixel data of the current frame, wherein the adaptive resolution management mode is disallowed. Related apparatus, systems, techniques and articles are also described.
